func FilterSupportReloadActionConfigSpecs added in v0.8.4 

func FilterSupportReloadActionConfigSpecs(metas []ConfigSpecMeta, volumes []corev1.VolumeMount) []ConfigSpecMeta

FilterSupportReloadActionConfigSpecs filters the provided ConfigSpecMeta slices based on the reload action type and volume mount configuration. It handles two types of updates to ConfigMaps:

1. Async mode: KubeBlocks controller is responsible for updating the ConfigMap, while kubelet synchronizes the ConfigMap to volumes. The config-manager detects configuration changes using fsnotify and executes the reload action. This requires volume mounting the ConfigMap. However, in async mode, if the volume mount is a subpath, kubelet does not synchronize the ConfigMap content to the container (see kubernetes/kubernetes#50345). As a result, the config-manager cannot detect configuration changes and does not support dynamic parameter updates for such configurations. Therefore, async-type ConfigSpecs with subpath volume mounts need to be removed.

2. Sync mode: For sync mode (regardless of the reload action type - TPLScriptType trigger or ShellType trigger), the controller directly watches the ConfigMap changes and actively invokes the reload action.

Both async and sync types need to pass the ConfigSpecs to the config-manager.

The check logic is an OR condition: either it is the first type (sync mode) or the second type (async) with a non-subpath volume mount configuration.
